I wanted to take a brief moment to say thank you. I took your 3-day homicide investigations course and 4 days later, my office caught a month old homicide with a body found in a creek. Using the tactics and techniques that you taught us, we were able to solve the case within 48 hours. During that time, we made four arrests and recovered 2 murder weapons hidden across our valley. We also used the lead sheet that you provided to help ease the flow of information in our investigation. The knowledge and life experience you offered in your course lead us to think outside the box and try several next tactics that lead to solid non-confrontational interviews and good arrests. Thank you for your class and knowledge.

“I just completed and passed the WZ final test and printed out my certificate. The course is outstanding! The voice over is excellent. The course content is extremely well done and valuable. I believe every person who conducts interviews/interrogations should take the WZ Investigative Interviewing course.”

First of all, I appreciate your time, your caring, and your love for teaching. It is obvious that you are in this game to create lethal interviewing machines. I have a great appreciation for that as well. Two days with you we’re certainly enjoyable. The absolute BEST part about our training was that after class it’s all we could talk about! We ate dinner each night practicing what we learned the previous day. We could see in each other that we will, over time, be able to perfect the methods you taught us.

It is important that we stay current with interview techniques, and this training provided all of us an avenue for conducting non-confrontational interviews, as well as non-verbal communications and many other indicators of deception. All of us are in agreement that this training provides a much broader knowledge than any other Interview and Interrogation Training we have attended and prepares us to conduct more thorough interviews in the future. The instructor, John Guzman, is a retired Investigator from the Chicago Police Department. His years of knowledge filled the training room with instant credibility that emitted throughout the three days of training.
